The Structure of Advanced Converters in Rechargeable Hybrid Electric Vehicles

Abstract

The main goal of this article was to compare advanced converters in plug-in hybrid electric vehicles. In this article, there are two examples of integrated chargers, the first charger integrates two DC/DC converters and uses the obtained converter in the structure of the charger, and the second charger integrates two power converters and inverters. It introduces a second integrated charger. These two chargers were simulated using valid references and compared with each other and finally the results showed that the second structure is a better structure in the car. The second structure reduced the volume, consumption, charging cost and losses by reducing the power electronic elements. This structure also had a better and higher capacity than the first structure. When it comes to getting the battery voltage to a high enough level to power the motor, the performance of the two structures was not much different, but in all other cases, the second structure performed better than its counterpart. Therefore, it is better and more economical to use this converter in rechargeable hybrid cars.
